IT’S not over until it’s over for Chelsea Handler and her boss-boyfriend Ted Harbert. The couple spent last weekend at the Water Club at the Borgata in Atlantic City. Sources say that despite reports of a split, the host of E!’s “Chelsea Lately” and her beau shared a suite and dined at restaurants Fornelletto and Bobby Flay Steak. A spy told us, “They were inseparable and did everything together.” Comcast CEO Ted even went to every one of Chelsea’s three shows at the casino-hotel.
